Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

Learners perform an experiment to determine which source of gas (their breath, exhaust from a car, or the air in the classroom) has a greater concentration of carbon dioxide. Students compare the colors of BTB solutions after...

Students observe what occurs when Alka Seltzer tablets are added to water. They explain why water stays in the jar when it is above the surface of the water. Pupils test for the presence of carbon dioxide by conduting the match test.

Pupils compare 4 different form of carbon dioxide and discuss the role that carbon dioxide has in the Greenhouse Effect. They then understand that the Greenhouse Effect is a naturally occurring event.

Seventh graders observe and test for the presence of carbon dioxide gas. They compare concentrations of carbon dioxide gas and conclude high concentrations of carbon dioxide gas are unhealthy for human beings.

Students explore oxygen properties by conducting a cell experiment in class. In this respiration lesson, students discuss the process of breathing and how oxygen is inhaled before carbon dioxide is exhaled. Students utilize yeast, water,...

Students explore the concept of air density. In this air density lesson, students fill balloons with helium and carbon dioxide. Students determine which gases are heavier or lighter than air.

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Fifth graders perform experiments to determine the identity of an unknown gas sample. In this chemistry lesson, 5th graders fill balloons with air, oxygen, hydrogen, and carbon dioxide. They use mass and reactivity to identify the gases.

Students experiment to determine which bottle of soda has more dissolved carbon dioxide. In this solutions lesson, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify and explain the...

Learners investigate gases and their properties by completing 4 activities. In this gases lesson plan, students perform activities to show that gases take up space, they diffuse, and that odors and vibrations pass through gases. They...

High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

Students analyze the function of the lungs. In this instructional activity about the Respiratory System, students explore breathing and the movement of air through the lungs. Students perform an 4 part experiment to observe what it might...

Students study yeasts or cellular respiration in this inquiry activity. They examine different types of bread to show which rise or do not. They measure the amount of carbon dioxide released by the yeasts when using different sweeteners.

Students list conditions necessary for humans to survive. They then mix yeast with a nutrient broth consisting of warm water and table sugar in a plastic bottle, capping it with a party balloon and compare the factors within the bottle...

Students experiment to determine if yeast is a microorganism. For this yeast blowup lesson, students mix yeast with other ingredients and observe the results by using a balloon. Students adjust the amounts of the ingredients and test...

Students observe yeast fermentation using different energy source. In this chemistry instructional activity, students measure the gas collected in the balloon. They upload their observations on the internet so they can share it with kids...

Students explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

Meteorology learners explore the weight of air, layers of the atmosphere, and air pressure action through a series of discussions, demonstrations, and hands-on group activities. Enough discussion prompts, background information, student...

Students name the main components of the respiratory system. They write a reaction that contains complete sentences, and uses proper spelling and grammar, after viewing a video. Students define the following terms: lungs, respiration,...

What do your vital signs tell your doctor? An engaging hands-on lesson has your learners monitor their own lung capacity, blood pressure, and heart rate. They then connect the vital measures to the workings of the circulatory and...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Here is an interesting and engaging lesson on the lungs and the respiratory system. In it, fourth graders should gain a better understanding of how the lungs work and the role they play in supporting life. Some good, in-class partner...
